Temperatures and rainfall come from NOAA’s gridded climate normals for Towaco itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Oak Ridge Rsvr, NJ (11 mi, snow) and Boonton 1 Se, NJ (4 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000. Today’s forecast: National Weather Service.
